Answer
HashMap offers average constant time complexity for get and put operations.
HashMap is generally faster than TreeMap because it uses hashing to store data, which allows for constant time complexity on average. In contrast, TreeMap uses a Red-Black tree structure, which provides logarithmic time complexity. In large datasets, this makes HashMap more efficient when order is not a concern.
